CNC_RDSPDLSPEED | POSITION

Description

This function does the calculation for serial spindle by which the gear ratio was considered against the rotation speed of spindle motor. And the approximate values of spindle speed(rpm) for numbers of spindle which was specified by specified spindle or parameter are returned.
But, only the first spindle becomes effective when there is no option of the multi spindle. In this function, the spindle speed is calculated by the following calculation expression.

Spindle speed = Real speed(rpm)

Maximum speed(rpm)
* Maximum speed to gear(rpm)

* The error might be included because of the approximate value calculation.

To calculate the spindle speed correctly by the above calculation expression, it is necessary to set a correct value in the maximum speed(rpm) of spindle motor and the maximum speed(rpm) to the gear as follows. And the gear number under use must be notified to DI signal correctly.

Declaration

#include "fwlib32.h"

FWLIBAPI short WINAPI cnc_rdspdlspeed(unsigned short FlibHndl, short spdl_no, short gear_no, long *spdl_speed);

Arguments : HSSB

FlibHndl   [ in ]

Specify the library handle. See "Library handle" for details.

spdl_no   [ in ]

Specify the spindle number which wants to be acquired.
Specify -1 or spindle number(1-4).
When -1 is specified, the spindle speed(rpm) from 1st spindle to the spindle setted by the parameter is acquired.
If the spindle number not set by the parameter is specified, the return value becomes an error(EW_NUMBER).

gear_no   [ in ]

Specify the gear number used by PMC spindle output control.
Specify the value of 1-3. If you specifies excepting 1-3, the return value becomes an error(EW_ATTRIB).
Moreover, only when all of undermentioned condition 1)-3) are satisfied, this argument is used as a gear number.

    1) No multi spindle option with M system
    2) Select the gear selection mode M type
    (Without constant surface speed control option, Parameter No.3706#4=0)
    3) Signal G033#7 is 1. (The spindle is being controlled with PMC.)
spdl_speed   [ out ]

Pointer to variable to store the spindle speed(rpm).
When you specify -1 for spindle number(spdl_no), prepare the array for amounts of the spindle setted by the parameter, and specify the top pointer.

Return

EW_OK is returned on successful completion, otherwise any value except EW_OK is returned.

The major error codes are as follows.

Return code Meaning/Error handling
EW_NUMBER
